[ARMDDK]: Use the same KPCR structure on ARM as on x86.
[ARMDDK]: Use the same addresses for KPCR and KUSER_SHARED_DATA on ARM as on x86. On ARM however, since there are no "segments", the KPCR is also mapped in user-mode, read-only, to have a static structure that can point to the current TEB. svn path=/trunk/; revision=45511
